Another dopamine-related fear and anxiety related gene,
COMT Genetic Variation Affects Fear Processing: Psychophysiological Evidence.
ScienceDaily with the predigested form. Quick points,
1) It looks like the SNP in question does
show some variation world wide. Europeans seem to have a higher frequency of the MET/MET genotype than Africans, while Asians tend to be lowest.
2) I notice that some genes around this locus show up as being under selection in
Haplotter. Within +/- 1.5 megabases.
3) This locus is implicated in a
lot of other stuff.
4)
